Hitesh Shah commented on YARN-5759:
-----------------------------------
Will this address support for a post-app action executed by YARN after the
application reaches an end state? i.e. somewhat like a finally block for a yarn
app?
> Capability to register for a notification/callback on the expiry of timeouts

> Key: YARN-5759
> URL: https://issues.apache.org/jira/browse/YARN-5759
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Reporter: Gour Saha
>
> There is a need for the YARN native services REST-API service, to take
> certain actions once a timeout of an application expires. For example, an
> immediate requirement is to destroy a Slider application, once its lifetime
> timeout expires and YARN has stopped the application. Destroying a Slider
> application means cleanup of Slider HDFS state store and ZK paths for that
> application.
> Potentially, there will be advanced requirements from the REST-API service
> and other services in the future, which will make this feature very handy.
